| 摘 要： | 凡口铅锌矿是发育于海相碳酸盐岩建造中的海底热泉喷溢沉积矿床。在研究矿床地质特征和地球化学特征的基础上，总结了发育于同沉积断裂两侧的矿体的形态、产状，矿石组构，成矿元素、微量元素、稀土元素的组成与分布，成矿温度和流体的性质，提出了热泉成矿作用与海相碳酸盐沉积作用同时演化的结论。

| Abstract: | The Fankou Pb_Zn deposit, most important one of stratabound deposits in North Guangdong Province, China, is a sedimentary_accumulative deposit of ore_bearing hot_springs. On the basis of the study of geology and geochemistry, and the summarization of the metallogenic and geochemical characteristics of the Fankou Pb_Zn deposit formed by the submarine hot_springs, the authors suggest that the mineralization and the precipitation of the carbonate are developed at the same time. |
